Rendition launcher for Quake II with game-folder selection, SGL2, original SGL and native OpenGL renderers, instruction set, 32-bit or 64-bit engine, resolution, and fullscreen settings.

Using the launcher

  1. Extract the entire ZIP.
  2. Run RenditionLauncher.exe.
  3. Click Find automatically, or Browse for game and select your classic Quake II folder.
  4. Choose SGL2, original SGL, or OpenGL for your GPU, set your display options, then click Launch.

Choose 32-bit or 64-bit Quake II for SGL2 and GPU rendering. Original SGL uses the 32-bit engine.

Manual setup

  1. Copy Drivers\x64\SGL2.dll into your classic Quake II folder as SGL2-x64.dll.
  2. Open Command Prompt in that Quake II folder and run:
"C:\path\to\RenditionLauncher\Engine\x64\quake2.exe" +set vid_ref gl +set gl_driver SGL2-x64.dll

Replace C:\path\to\RenditionLauncher with the folder you extracted. Keep ref_gl.dll and gamex64.dll beside the bundled 64-bit engine. For the original driver, copy Drivers\SGL.dll and run Engine\quake2-custom.exe with +set vid_ref gl +set gl_driver SGL.dll.
